I The present invention relates to a machine for polishing the ends offines and cutting off the fag ends at one operation.

In recent years, the method of reclaiming fiues by welding on a piece ofnew material to the old flue is being done by the electrical process,whereas'the former'method was to use oil furnaces forwelding. In thiselectric Welding process, it is necessary that the end of the old fluebe cleaned sulficiently so that contact may be made properly be tweenthe electrodes. Itis also necessary to out off the fag end of the fluein order to accommodate the welding on of the new piece. In order toeffect economy inthese operations, this machine is designed to performtwo operationsv simultaneously.

Another very important object of the invention residesin the provisionof a machine of this nature wherein the parts are arranged in a compactand convenient manner and are simple in their construction.

Another important object of the invention resides in the provision of amachine of this nature which is comparatively inexpensive to manufactureand operate, is thoroughly eiiicient and reliable in its operatiom'andis not likely to easily become out of order.

WVith theabove and numerous other objects in View as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as V willbe hereinafter more fully described and claimed.

In the drawings: Figure 1 is a side elevation of the ma chine embodyingthe features of my inven tion,

Figures 2 and 3 are vertical transverse sectionsxtaken substantially onthe lines 22 and 3+3 respectively of Figure 1,

Figure 4 is a vertical fragmentary longi-i tudinal section takensubstantially on the line 1& of Figure 3, and v Figure 5 is a detailhorizontal section taken substantially on the line 55 of Fig- :ure 4.

Referring to the drawingin detail it will be seen that the numeral 5denotes an elongated base having supports and 7 rising from'one endthereof in spaced relation for supporting a platform 8. An electric m0..

tor 9 is mounted on the platform8. A beai ing bracket 10 rises from thebase 5 within the support 6 and has journaled in its upper end ahorizontalshaft 11 which is operatively connected with the motor9"throughi'an endless chain and gear. mechanism 12 or. in any otherpreferred manner. 'A shaft leis operatively connected with the shaft 11by means of a universal'joint so that the shaft 14 extends through thesupport/Z. Frames 15 and 16 rise fromadj'acentthe other end'jof theplatforin'5 and have slidable vertically therein cross'heads 17 and 18,respectively. The inner vertical side edges of the frames 15 and 16 .areformed with longitudinally extending'ribs 19 and the cross heads may bemade in two sections a bolted together as at Z) and having their outerside edges recessed to form channels or grooves 0 to receive the ribs19. A pair of rotatable cleaning elements are mounted between the frames15 and 16 at their lower ends. These rotatable cleaning elements, are inthe form of; cylindrical rollers 20 having spiral cutting ribs 21 formedon the peripheries'j thereof, the cutting rib of one roller 20 bei .ngspiralled oppositely to thatofthe other as will be apparentfrom aninspection of Figure :5. These rollers '20 have their aXes "disposedhorizontally and in' spaced parallelism to each other. V V

The sections a ofthe cross head 5 are provided with depending ears dinwhich are journaled the trunnions 23 of a roller 24: disposed betweenthe ears (Z and projecting slightly therebelow. Cylinders) 25 mounted onthe. tops of the frames. 15 and 16jbeing boltedin place as at 26 andhaving pipes 27 leading from'the tops thereof Pistons 28 are slidable inthe cylinders 25 and v have rods 29 depending downwardly therefrom andslidable through openings 30in the tops of the frames 15 and 16. Thelower ends of these rods'29 terminate inhca'ds 31.

' The abutting surfaces of the sections aiof the cross heads 17 and 18are recessed as is indicated at 32 for receiving thehe'ad's 31 where-'are ders through the pipe 27 so as tourge the cross heads 17 and 18downwardly. The

end of the flue to be cleaned isplaced on the rollers 20 and theroller-18 rests thereon The electric mo-,

as does also the cutter- 34.

'tor 9is energized simultaneously with the turning on ofthe,fluid}pressure so that as the rotary cutter 34 rotates, the cross headsc1-7fand l8 are'forced downwardlyso thatthe 20 rotary motion of thecutter '34 is transmitted tothe flue and the rotary ,{motion of the flue"is transmitted to the roller24and the cleaning rollers 20. The rotationof theseclean- *ingv rollers 20 willcausej the spiral ribs 21 tothoroughly c lean the-exterior surfaces of ."the'flu'e andsimultaneously the cutter 34 will be cutting off the cruise as toeliminate theflfagmendsottheflue! As soon as the cutter severs theflueqthe flue will cease to i so rotate, and the 'fluid pressure and themotor should becutofl. f a

It is thought that the construction, operation, utility, and advantagesof this inventionwi-ll now be quite apparent to those :s'killedfin thisart Without a more detailed descriptionthereof." The present embodimentof the invention has been disclosed by way of example because in. actualpractice it atthefeatures of advantage enumerated as desirable in thestatement of the invention pa ndlthe'above description. "It will beapparen't,"however, that changes in the details-oi constraction, and inthe combination and arrangement of ,parts maybe resorted to without.departing'from the spirit of the inven- -tion or scope thereof, ashereinafter claimed orsacrlficmgany ofltsadvantages.
